Electron >=20 with ELECTRON_RUN_AS_NODE: TypeError: Cannot convert undefined or null to object

[Prinzhorn]

I've searched the ava repo, electron repo and the web. Apparently I'm doing something exotic.

Starting with Electron 20 I can no longer run my tests with ava. I don't know what exactly broke it and if I need to change something or them.

My npm script:

"ava": "ELECTRON_RUN_AS_NODE=true electron ./node_modules/.bin/ava src",

npm run ava gives

node:internal/modules/esm/translators:178
      if (!ObjectPrototypeHasOwnProperty(exports, exportName) ||
           ^

TypeError: Cannot convert undefined or null to object
    at hasOwnProperty (<anonymous>)
    at ModuleWrap.<anonymous> (node:internal/modules/esm/translators:178:12)
    at ModuleJob.run (node:internal/modules/esm/module_job:198:25)

    at async loadESM (node:internal/process/esm_loader:88:5)
    at async handleMainPromise (node:internal/modules/run_main:61:12)

Minimal repo steps are easy in an empty folder:

1. npm i electron@19 ava
2. ELECTRON_RUN_AS_NODE=true ./node_modules/.bin/electron ./node_modules/.bin/ava
3. Works (can't find any tests obviously)
4. npm i electron@20 (or anything up to the most recent 23.0.0-beta.3)
5. ELECTRON_RUN_AS_NODE=true ./node_modules/.bin/electron ./node_modules/.bin/ava
6. Gives the error

Turns out this is a bug in Electron (they fiddled with the ESM loader), I just need to repro it without ava. Broke between 20.3.1 and 20.3.2.
